Medical ultrasound, also known as sonography, is a diagnostic imaging technique that utilizes high-frequency sound waves to create images of internal structures within the body. It is a non-invasive and safe procedure commonly used in various medical fields, including obstetrics, cardiology, and abdominal imaging. ### Key Features of Medical Ultrasound: 1. **How It Works**: A device called a transducer emits high-frequency sound waves that travel through the body and reflect off tissues and organs.

Speckle tracking echocardiography (STE) is a cardiac imaging technique that allows for the assessment of myocardial deformation (strain) by tracking the motion of acoustic speckles in ultrasound images. Instead of just providing information about the heart's structure and function through standard two-dimensional or three-dimensional echocardiography, STE provides insights into the heart muscle's ability to stretch and contract.
Tissue Doppler echocardiography (TDE) is an advanced echocardiographic technique used to assess myocardial (heart muscle) function. It utilizes the Doppler effect to measure the velocities of the heart muscle as it contracts and relaxes, providing critical information about the health and function of the heart.
Ultrasound-enhanced systemic thrombolysis is a medical procedure that combines traditional systemic thrombolytic therapy with the use of ultrasound technology to enhance the breakdown of blood clots. This technique is primarily used in the treatment of conditions like acute pulmonary embolism, myocardial infarction (heart attack), and severe deep vein thrombosis.
Nuclear medicine physicians are medical doctors who specialize in diagnosing and treating diseases using radioactive materials and imaging techniques. They utilize a variety of nuclear medicine procedures, which often involve the administration of small amounts of radioactive substances to patients. These substances help in the visualization of physiological functions and processes within the body.
A cardiac stress test, also known as an exercise stress test or treadmill test, is a medical procedure used to assess how well the heart functions during physical activity. The test typically evaluates the heart's response to stress, which can help detect various cardiovascular conditions. Here’s an overview of the procedure and its purpose: ### Purpose of a Cardiac Stress Test 1. **Diagnosing Heart Conditions**: Helps identify issues such as coronary artery disease, arrhythmias, or other cardiovascular problems.
Pentetic acid by Wikipedia Bot 0
Pentetic acid, also known as diethylenetriamine pentaacetic acid (DTPA), is a chelating agent that binds to metal ions. It has a chemical structure that enables it to form stable complexes with various metal ions, which is useful in several applications. DTPA is commonly used in medicine, particularly in the treatment of heavy metal poisoning, as it can help to remove toxic metals like lead, mercury, and plutonium from the body.
Hair removal by Wikipedia Bot 0
Hair removal refers to the process of eliminating unwanted hair from the body. This can be done using a variety of methods, each with its own advantages and disadvantages. Common hair removal techniques include: 1. **Shaving**: Using a razor or electric shaver to cut hair at the skin’s surface. It's quick and easy but may lead to irritation or ingrown hairs.
Laser ablation by Wikipedia Bot 0
Laser ablation is a process in which material is removed from a solid (or occasionally liquid) surface by irradiation with a laser beam. The laser energy is focused onto the material, causing it to heat and vaporize, or to be ejected in particles or as a plume of vapor. This technique is widely used in various fields, including materials science, surface engineering, and medical applications.
Mode locking by Wikipedia Bot 0
Mode locking is a technique used in lasers to generate short pulses of light (typically in the picosecond to femtosecond range) by forcing different longitudinal modes of the laser cavity to oscillate in phase. In a typical laser, multiple longitudinal modes (which are different frequencies of light that can oscillate in the cavity) can be present, but they may not be in sync with each other. This lack of synchronization results in a continuous wave output.
The Pascal Photocoagulator is a type of laser device used primarily in ophthalmology for the treatment of various eye conditions, particularly those involving the retina. The term "Pascal" refers to the specific technology used in the device, which allows for a more efficient and effective method of laser photocoagulation. Photocoagulation is a procedure that uses laser energy to create small burns in specific areas of the retina.
Schwind eye tech solutions is a company that specializes in developing advanced technologies and equipment for ophthalmology, particularly in the field of refractive surgery and diagnostics. They are known for their innovative products used in procedures such as LASIK (Laser-Assisted in Situ Keratomileusis) and other vision correction techniques. The company focuses on precision, safety, and effectiveness in eye care, providing surgeons with state-of-the-art tools to improve patient outcomes.
Diagnostic medical imaging is a field of medicine that uses various techniques and technologies to create visual representations of the interior of a body for clinical analysis and medical intervention. The primary purpose of diagnostic imaging is to diagnose, monitor, and treat diseases and conditions by providing detailed images of organs, tissues, and other anatomical structures.

Cephalometry by Wikipedia Bot 0
Cephalometry is a scientific discipline that involves the measurement of the head, typically the human skull, to analyze its dimensions and shapes. It is primarily used in orthodontics, anthropology, and forensic science to assess craniofacial structures. Cephalometric measurements can provide valuable information about the relationships between facial features, the growth patterns of the skull, and deviations from normal anatomical proportions.
A computational human phantom is a digital or virtual representation of the human body used in various fields such as medical imaging, radiation therapy, and dosimetry.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
